I made a Cursor for prompts and tools

https://promptslice.com
2•joshmlewis•21h ago
I was tired of having to copy/paste my prompts for agents I'm building into various places and tired of ChatGPT/Claude totally mangling it when I ask it to do one simple change so I built this. Tool definitions + your prompt are a huge part of success rate yet no one really tests them together or tries to optimize.

I'm planning on adding automated evals for your prompts + tool definitions against whatever models you want each time you make a change. Want to know how "dumb" of a model you can get away with? I want to add that as an option too. New model comes out and you need to see how it'll do? You get the idea.

I don't have billing/pricing setup yet which is why it's on the waitlist but sign up and I'll let you in to test it out and give feedback.
